HPMSM Programme

Eryvium's HPMSM Programme upgrades qualified manganese sulphate materials into two battery-grade products: ultra-high-purity HPMSM at 99.99% (4N) and battery-grade HPMSM at 99.98% — manganese precursors for NMC, manganese-rich, and LMFP cathode chemistries. Pilot-stage technical work is completed, with first commercial production targeted within twelve months.

Clean Feedstock, Proven Process

Eryvium is bringing a commercial HPMSM programme to market, built for reliability, clean operations, and disciplined scale-up. The process starts from qualified manganese sulphate materials and upgrades them to two grades — ultra-high-purity HPMSM at 99.99% (4N) and battery-grade HPMSM at 99.98% — through a proprietary technical route.

Our approach prioritises defined input quality, simpler flowsheets, and efficient impurity control. Capacity expands with customer demand toward a combined target of 24,000 tonnes per annum across the United States and Europe, building regional supply security.

ESG Commitment: Near-zero-waste objective through residue valorisation, progressing toward ISO 9001 / ISO 14001 certification, and full alignment with EU environmental standards. Low carbon intensity: a specialty manganese-chemistry route with modelled process emissions of approximately 0.50–0.60 kg CO₂e per kg HPMSM (plant-only basis), declining further with low-carbon energy. A full cradle-to-gate life-cycle assessment is in completion.

Note: The two HPMSM grades are produced on a single proprietary technical backbone and are demonstrated today. Battery-grade manganese carbonate (MnCO₃) is a product extension currently in development. Final specifications confirmed per customer qualification. Verification by ISO/IEC 17025-accredited laboratories using ASTM/ISO analytical methods.

Process Overview

A disciplined flow from clean feedstock through targeted purification to battery-grade product.

Qualified industrial-grade MnSO₄·H₂O reception → targeted multi-stage impurity removal → battery-grade specification achieved through proprietary multi-stage purification and crystallisation.

Capacity designed for staged, rapid deployment → near-zero-waste objective through residue valorisation → output scaling with customer demand toward 24,000 tonnes per annum.

Progressing toward ISO 9001 / ISO 14001 certification → EU and host-country regulatory alignment → independent ISO/IEC 17025-accredited laboratory testing using ASTM/ISO analytical methods.

Process Overview

HPMSM for Cathode Qualification

Battery-grade HPMSM at 99.98% and 4N HPMSM at 99.99% for Western cathode supply chains

Request Data Sheet

Battery-Grade Quality

Two grades — ultra-high-purity HPMSM at 99.99% (4N) and battery-grade at 99.98% — for advanced cathode chemistries including NMC, manganese-rich, and LMFP formulations.

Regional Supply Security

Shorter, more transparent supply chains for Western customers — battery-grade manganese precursor supported by US and European production-route preparation.

99.99% (4N) HPMSM

Clean Operations

Lower reagent intensity and simpler flowsheets reduce environmental footprint. Clean feedstock approach enables smoother permitting and regulatory compliance

Staged Growth

Capacity can expand with market demand. Phased deployment reduces capital risk while enabling rapid response to customer requirements
